Portable Gas Detector, Gas Clip 4 Gas Monitor Meter Tester Analyzer, Rechargeable LCD Display Sound Light Shock Air Quality Tester, 2 Year Detector…

Works great for my job

Why did you pick this product vs others?:detects farts, didn't know what else to test with, but it appears to work and cover a range of concerning gases.

I just purchased my second one of these. The first the oxygen sensor went bad but that was not unexpected. If you shop around you'll find that all of the oxygen detectors have sensors with about a 24 month lifespan. This one lasted me over two years. And if you check you'll find out the more expensive devices that offer replacement oxygen sensors charge more for those sensors than you will pay for this entire device. Also you can turn the oxygen high alarm up to its upper limit and the low alarm to its lower limit and not have to listen to the alarm. This makes the unit capable with regard to the three other sensors so it's not a doorstop. And if that's not enough you can throw the thing away and still have a snazzy aluminum box that you can use for your jewelry or whatever. You also get a USB charger and cord.

My husband is Safety Manager for a mid size oil and gas company. They have many drilling sites. They are using these on every pad. I believe the company has purchased maybe 35 SO FAR!! Thanks for the product. ETA BATTERIES ARE NOT KEEPING A CHARGE. WON'T ORDER ANYMORE.

I bought this is 2021. Maybe they programmed it to stop working after a while? Maybe the oxygen sensor degrades over time?In any case, over 100$ spent and the thing is useless. All four values read 0 ppm or 0.0%. I have charged, restarted, tried every setting in the settings. I can set the alarm for low oxygen to 0.1% but since it consistently reads 0.0%, the alarm keeps going. Cannot be muted, which is probably a safety feature, but when the alarm is faulty, and you cannot override it, it is really annoying. While trying to troubleshot it, I found the alarm mutes after something like 10 minutes. Switching off then on again, the audio comes back on.I would rather have the alarm serviced than just throw it out, but how to do that?In either case, it worked when I bought it, but now that I need it, it stopped working.No, I would not recommend buying this unit.

I explore abandoned PA coal mines and use this in conjunction with a safety lamp to detect hazardous gases. It's alarm hasn't sounded yet and I'm still alive so I assume it's working properly. Other than that I have no way to determine it's accuracy. It's inexpensive enough to buy a new one every 2 years and keep the old one in my pack as an emergency backup

Turned the meter on in my home and it appeared to be working normally, reading 20.9% O2. Took it to the mountains and into some old mines as a test and it was reading anywhere between 9-16% O2 both above and underground, all of which would be fatal. No sure if I got a defective or uncalibrated unit but I returned it, not trusting my life with something this unreliable. Also got a "save failed" message multiple times when attempting to adjust various alarm settings on the meter.

I feel this is a quality product for the price. Find that it has to be charged every night Before you use it. Does not hold charge if charge it days before you need it.
